DevTools: Better linking between browser Performance tab and DevTools Profiler

Notes from a chat with Benoit: It would be nice if starting profiling (or reload and profiling) in the browser auto-started profiling in DevTools. It would also be nice if viewing a range of time in the Performance tab narrowed down the commits within the Profiler. At least starting the profilers at the same time would enable a manual match-up. To my knowledge, none of the currently available APIs (including experimental) would enable us to support this level of integration. --- If we were to make use of the DevTools protocol, we could [`Profiler.start`](https://vanilla.aslushnikov.com/?Profiler.start) and [`Profiler.stop`](https://vanilla.aslushnikov.com/?Profiler.stop) the built-in profiler in sync with React's own profiler. Chrome's profiler also dispatches [`Profiler.consoleProfileStarted`](https://vanilla.aslushnikov.com/?Profiler.consoleProfileStarted) and [`Profiler.consoleProfileFinished`](https://vanilla.aslushnikov.com/?Profiler.consoleProfileFinished) events which we _could_ use to follow the browser's profiler if we wanted to. There do not appear to be any APIs/events for syncing the zoomed-in range. --- Originally reported via https://github.com/bvaughn/react-devtools-experimental/issues/37
